Abstract

The invention relates to the technical field of polyurethane adhesives, in particular to a single-component thermoplastic polyurethane adhesive and a preparation method thereof. The single-component thermoplastic polyurethane adhesive is prepared from a polyurethane prepolymer, a filler, a solvent, a catalyst, a thickener and an antioxidant; according to the single-component thermoplastic polyurethane adhesive prepared by the invention, by adding the filler, the yield of the adhesive can be increased, the cost can be reduced, the use performance such as the shrinkage rate can be improved, thehardness, the strength and the elasticity can be improved, the added antioxidant has good extraction resistance, high thermal stability and long persistence, can be used as a stabilizer during adhesive processing, meanwhile, thermal oxidative degradation of the adhesive in the long-term aging process is prevented, the added fumed silica small particles form a network structure to inhibit colloid flowing, the curing speed is increased, the bonding effect is improved, the sealing performance and the impermeability of the product are also improved, and meanwhile, the fumed silica small particleshave a certain effect on thickening of a glue solution as a rheological additive in processing.

Description

technical field

[0001] The invention relates to the technical field of polyurethane adhesives, in particular to a single-component thermoplastic polyurethane adhesive and a preparation method thereof. Background technique

[0002] Polyurethane adhesive is an important part of the rapidly developing polyurethane resin. It has excellent performance and has been widely used in many aspects. It is one of the important varieties among the eight synthetic adhesives. Polyurethane adhesive has excellent shear resistance Shear strength and impact resistance, suitable for various structural bonding fields, and has excellent flexibility, not only strong adhesion, but also excellent cushioning and shock absorption functions, low temperature and ultra-low temperature of polyurethane adhesives The performance exceeds all other types of adhesives. Thermoplastic polyurethane adhesives are synthetic polyurethane adhesives made of thermoplastic polyurethane. They soften and bond when heated, ...
